I was contacted by a guy who lost his ring while swimming in Powers Lake near a floating trampoline. He had a pretty good idea of where it was and the water was only about 6ft deep but with all of the weeds and the muck in the area it made it hard to see clearly to the bottom. The floating trampoline was his landmark however the trampoline could moved close to 10ft in any direction. After an hour and a half of searching with scuba gear, the ring was located right by the trampoline.
